Abstract

CuO/MgO catalysts with various shapes have been obtained by using morphology-controlled synthesis technology. It is demonstrated that there is a remarkable difference in catalytic activity for CO oxidation among these samples. However, when all these catalysts react with water before calcination, their shapes become irregular and similar, consequently, the difference of their catalytic activities disappears.

摘要

通过使用形貌控制合成技术获得了具有各种形状的CuO/MgO催化剂。结果表明，这些样品对CO氧化的催化活性存在显著差异。然而，当所有这些催化剂在煅烧前与水反应时，它们的形状变得不规则且相似，因此，它们的催化活性差异消失。
